MMT - Select AES3 transmitter mono or stereo operation
MMTCS - Select A or B channel status data to transmit in mono mode
MMTLR - Channel Selection for AES Transmitter mono mode
12.3 Data Flow Control (3h)
The Data Flow Control register configures the flow of audio data to/from the following blocks: Serial Audio Input Port,
Serial Audio Output Port, AES3 receiver, and AES3 transmitter. In conjunction with the Clock Source Control regis-
ter, multiple Receiver/Transmitter/Transceiver modes may be selected. The output data should be muted prior to
changing bits in this register to avoid transients.
TXOFF - AES3 Transmitter Output Driver Control
AESBP - AES3 bypass mode selection
TXD1:TXD0 - AES3 Transmitter Data Source
SPD1:SPD0 - Serial Audio Output Port Data Source
